frequent sudden reboot, sometimes system hanging
In October 2021 one of my three NUC's suddenly stopped after having performed flawlessly since January 2020. I had it repaired under warranty and it came back with a new motherboard. I put in the memory and drives. All seemed fine, but now it randomly reboots some time after I stop using it actively. When I come back some times it resumes normally, some times it appears to have rebooted or doesn't respond to mouse or keyboard activity and I have to force a hard shutdown. Some times the restart presents a GRUB menu, some times it just starts up normally.
In the system journal there is a BERT fatal failure reported in some cases, but not every time. [Hardware Error]: section type: unknown, 81212a96-
I wander whether the hardware is not good or is there some kind of incompatibility as the new motherboard is of a newer production date (5/2020) than the old one (11/2019).
I hope someone can help me find out what is wrong and how to fix it.
I am running Linux Mint on Ubuntu 18.04. Hardware is a NUC8BEH.
Linux version 4.15.0-162-generic (buildd@
